Chrome is default ...Again

I love firefox, and am very attached to it with my viewing history, bookmarks, autofills and Fancy add ons that i can't imagine the web without.
But, I usually use chrome when Firefox starts to run slow, planning to get back soon, but little by little I find my self opening more tabs on chrome than i have one firefox, and saving more to-read-later bookmarks, and before i know i find my self setting chrome to being the default browser...again
